BU1425AK

Series: -
Mounting Type: Surface Mount
Packaging: Tray
Manufacturer: Rohm Semiconductor
Voltage - Supply, Analog: 4.5 V ~ 5.5 V
Voltage - Supply, Digital: 4.5 V ~ 5.5 V
Type: NTSC/PAL Encoder

Supplier Device Package: 64-QFP-A


Features:

Input clocks supported
      27.0 / 13.5MHz
      28.636 / 14.318MHz
      28.375 / 14.1875MHz
      35.4695 / 17.73475MHz
24-bit RGB and 16-bit YUV input signals are supported.
Both master and slave systems are supported.
9-bit high-speed DAC is used for DAC output of composite VIDEO, Y, and C signals.
Internal 8-color OSD output function is provided.
FSC-TRAP on the Y channel can be turned on and off.
C channel is equipped with an internal chrominance band-pass filter in addition to the U.V. lowpass filter.
5V single power supply, low power consumption (0.4W typ.)
Y and C output can be turned off (the power consumption with Y and C off is 0.25W typ.).
In the Master mode, applying 3.3V to the I / O VDD and 5.0V to other VDDs produces HSY and VSY output with an amplitude of 3.3V. This enables direct connection to LSIs that use a power supply voltage of 3.3V. (The clock output for the OSD has a fixed amplitude of 5.0V.)
In the Slave mode, applying voltage to the I / O VDD only, and applying 0V to other VDDs, enables a current consumption of 0 even when RGB DATA, HSY, VSY, and OSD DATA are in the active state.


Application

Video interfaces for VIDEO-CDs and CD-G decoders
